Odds are it looks like it'll be either a spool of printing cable (PLA, ABS, Nylon, etc.) that you'll print with, or it'll be like you buy motor oil (UV Reactive polymers). These are FDM (reprap and the like) and SLA [1] techniques for 3D printing. So far the SLS (using a powder or sand) seems to be stuck in the very high commercial range though it can be the most useful, it requires far less fiddling with to get things to print out regardless of their shape like a reprap does, and can get very good material reuse like SLA does since unused material is just kept in the same state. It can also do one of the more fun things, combine SLS and an inkjet printer and you can color the object you're printing just like a normal printer [2].
